About this tool
This page opens the world clock with Sydney already added to the card list, on top of the tool’s own defaults: your browser’s time zone, UTC, New York, and Tokyo. Sydney’s current time, date, and UTC offset appear as soon as the page loads.
Sydney sits far enough east that its date is often a full calendar day ahead of the Americas and Europe, and its own clocks shift between daylight and standard time on a schedule opposite to the Northern Hemisphere — two things that make mental time-zone math for Sydney especially unreliable.
The clock refreshes every second, and the selector below the card list lets you add any other IANA time zone your browser knows about, so you can line Sydney up against a meeting, a match, or a release scheduled somewhere else.
Example. A browser in America/Chicago opens four cards: that zone, UTC, America/New York, and Asia/Tokyo. Each card is the current instant, and the seconds line is redrawn every 1000 ms.
Limit. The clocks show the present instant only. There is no remove button, added zones disappear on reload, and a background tab may delay the one-second timer.
